dc.description.abstractSe realizó un estudio de cohorte, que evaluó los niveles de exposición mediante la detección de anticuerpos específicos contra patógenos que causan problemas reproductivos, en muestras trimestrales de leche de cantina provenientes de 384 hatos del municipio de Guatavita, Cundinamarca. Se estimó la prevalencia de exposición a nivel hato de DVB, HVB-1, N. caninum, y L. hardjo y se evaluó la dinámica de los anticuerpos en el tiempo; se realizó una encuesta epidemiológica al inicio del estudio con un seguimiento a través de visitas veterinarias a 91 hatos para obtener la información de bioseguridad, eventos de enfermedad y manejo reproductivo para poder determinar los factores asociados a la exposición de los patógenos. La prevalencia de exposición para cada agente infeccioso fue de 60.1% en DVB, 25.7% para HVB-1, de 81.1% para N. caninum y 37.2% para L. hardjo. La tasa de incidencia (casos por cada 100 hatos/mes) a por cada trimestre para DVB fue 0.57, 0.78 y 0.48, para HVB-1; 0.39, 0.32. 0.28, N. caninum; 0.82, 1.18 y 0.24, L. hardjo 0.48, 0.37 y 0.24. Los factores asociados a la exposición a patógenos fueron: la compra de animales para DVB, la movilización indiscriminada de animales entre hatos fue un factor de riesgo para DVB y BHV-1; la baja tasa de descarte animal estuvo asociada al riesgo de exposición para N. caninum y los hatos que realizan monta directa tuvieron mayor riesgo de estar expuestos a L. hardjo. En análisis espacial mostró tener áreas de mayor riesgo de exposición en la zona central del municipio.
dc.description.abstractThe objective of the present study was estimated the prevalence of exposition and the incidence of herd level of Bovine Diarrhea Virus, Bovine Herpes Virus, Neospora caninum, y Leptospira hardjo in canteen milk samples from dairy herds in Guatavita, Cundinamarca. Additionally, it was evaluated the changes of the dynamics of the antibodies on the time of the infections mentioned and was identified factors associated with the exposition to different disease. It is a cohort study that evaluated herd level exposition by antibody determination in trimestral samples of milk from n=384 dairy herds. Epidemiologic questionnaires were used to gather information on management farm practices, biosecurity, reproductive diseases, and veterinary assistant to support the farms. The prevalence BVD infection was 60.1 per cent, of BHV-1 infection was 25.7 per cent, of N. caninum was 81.1 per cent and of L hardjo was 37.2 per cent. The incidence rate (cases per 100 herds / month) for DVB was 0.57, 0.78 and 0.48, for HVB-1; 0.39, 0.32. 0.28, N. caninum; 0.82, 1.18 and 0.24, L. hardjo 0.48, 0.37 and 0.24. The factors associated with exposure to pathogens were: An increasing the animal purchase increased the risk for having BVDV times 6.4 (IC 95%: 1.3-10.4 p=0.007). Animal movement between farms were risk factors for the presence of all two agents (BVD; RR=7.6; IC 95%: 1.7-16.7, p=0.021 and BHV-1; RR=3.7; IC 95%: 1.4 - 10.0, p=0.009). Low culling rate was associated with a 13.1 times increased risk for having N. caninum (IC 95%: 1.8 - 97.8; P<0.012). The presence of a bull was associated with a 5.2 times increased risk for having L. hardjo (IC 95%: 3.8-13.8 p=0.006). This study shows spatial clusters that are associated with the central region.
